What determines the number of hydrogens in an acid?
Answer:
It's the same as the charge of the anion
Explanation:
What determines the number of hydrogens in an acid is the charge of the corresponding anion. This is otherwise termed the Basicity of the acid
According to the question;
We are required to identify what determines the number of hydrogens in an acid.An acid is typically made up of an Hydrogen ion(Cation) and another anion.
For instance:
HCl is made up of 1 H+ ion and 1 Cl- ion.While, H2SO4 is made up of 2 H+ and one SO4²- ion.Read more:

A student found the mass of an object to be 5.5 g. The actual mass of the object is 5.3 g. What is the percent error in the measurement?
Answer: 3.6%
5.5 - 5.3 and divide it by 5.5. Then multiply this by 100
Explanation:
This will get you 3.6%
The percent error in the measurement is 3.774%
How do you calculate the percent error?
Subtract one cost from the other: 2.sixty eight - 2.70 = -zero.02.relying on what you need, you may discard any poor sign (take the absolute value): 0.02. that is the mistake.Divide the mistake by using the proper cost:zero.02/2.70 = zero.0074074.Multiply this fee by 100% to attain the percentage of mistakes:What's an example of a percent error?
For an instance, let's assume you guessed that there have been 230 gumballs within the picture, however, there were simply 311 gumballs. The distinction between your wager (230) and the actual wide variety (311) in the evaluation of the actual variety (311) expressed as a percentage is the percentage error.

the mass of an object changes when it goes through a physical or chemical change
Answer:
True.
But it only changes in physical change.
How?
Explanation:
The chemical reaction produces a new substance with new and different physical and chemical properties. Matter is never destroyed or created in chemical reactions. The particles of one substance are rearranged to form a new substance.
In a physical change, a substance's physical properties may change.
A chemical change is a permanent change. A Physical change affects only physical properties i.e. shape, size, etc. ... Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. A few examples of chemical change are digestion of food, burning of coal, rusting, etc.

(C,D)bondlengthtitle.gif The length of a covalent bond depends upon the size of the atoms and the bond order.For each pair of covalently bonded atoms, choose the one expected to have the shortest bond length.(A) Cl-I(B) I-I...... (A,B)(C) P-Br(D) P-Cl...... (C,D)
Answer:
See explanation
Explanation:
In the section A,B
C triple bond O has a higher bond energy. A triple bond is shorter and more difficult to break hence they have a higher bond energy.
For the same reason in the C,D section; C triple bond N has a higher bond energy.
In the next section, the higher the bond order the shorter the bond. Hence C triple bond C is the shortest in the A,B section while C triple bond O is the shortest in the C,D section. Both have a bond order of 3.
In the A,B section; I is larger than Br hence H-Br has the shortest bond length.
In the C,D section; Br is larger than Cl hence P-Cl has the shortest bond length.

Answer: .03 M
Explanation:
you have to use m1v1 = m2v2
but the units should be in L so we need to convert the 32.20 and 26.60 into L by dividing them by 1000. So now we have .0322 and .2660
.0322(.25)=(.2660)(x)

Which of the sets of elements are not in order of increasing force of attraction on the outermost electron in atoms of that element?
Ba < Sr < Ca
Al < P < Cl
F < Cl < Br
Mo < Pd < Sn
Answer:
The set of elements that are not arranged in the order of increasing ionization energy is Mo < Pd < Sn
Explanation:
The force of attraction on the outermost electron of an element can be described by the ionization energy of the element which decreases down a group and increases across a period
1) The given elements Ba, Sr, Ca, are group 2 elements arranged in the order from bottom up, which gives an increasing ionization energy, therefore;
Ba < Sr < Ca is arranged in increasing ionization energy, and therefore, increasing force of attraction of the outermost electron in atoms of the elements
Similarly, Al < P < Cl and Mo < Pd < Sn, are arranged in order of increasing ionization energy
However F < Cl < Br which are arranged from top down of elements in period 17 are arranged in the order of decreasing ionization energy, and therefore, decreasing force of attraction of the outermost electron in atoms of the elements.
The elements that are not arranged in their increasing force of attraction base on the outermost electron present in their atoms is D:
Mo < Pd < Sn.
Ionization energy of an element usually increase when moving along the period and decreases down a group and thus explains the force of attraction on the outermost electron.Option A are arranged in from down to up of group 2, which means they are in increasing order of ionization energy, same thing with option B, C. But option D, doesn't follow the arrangements hence, the correct answer.Therefore , option D is correct.

what event typically causes upwelling?
Answer:
Conditions are optimal for upwelling along the coast when winds blow along the shore. Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”

Answer:
He assumed wrongly
Explanation:
It happened this way because the person assumed wrongly.
Most other compounds have the same physical appearance as water especially when in liquid form.
This can be a very tricky one in the laboratory. The sense of taste is not the best way to fathom what a particular compound is made up of.

A cylinder at left with balls evenly spaced throughout the cylinder with an arrow leading to a cylinder at right with balls stacked near the bottom of the cylinder.
Which change of state is shown in the model?
condensation
deposition
boiling
freezing
Answer:
deposition
Explanation:
The model above shows a transition from a gas state to a solid state. This is known as "deposition."
The particles are widely-spaced on the left because they have a lot of energy; thus, they don't interact with each other. This is the reason why the gas doesn't have a definite shape and volume.
The particles on the right are stacked near the bottom because they don't have enough energy to move about; thus they interact with each other. This gives solid a definite shape and a definite volume. They can only move if the thermal energy increases.
