WHY IS A CREEP(creep as the science def) HARD TO DETECT ?( please need help to answer this question!!)
Answer:
Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock. Movement is caused by shear stress sufficient to produce permanent deformation, but too small to produce shear failure. ... Continuous, where shear stress continuously exceeds the strength of the material.

Calculate the mass of 120cc of nitrogen gas at ntp.How many number of molecules are present in it.Easy step of mole concept
Explanation:
The formula of nitrogen gas is given as;
N₂
Given volume of the gas = 120cm³
Now,
We need to find the number of molecules and the mass of this compound
Solution:
At STP;
1 mole of gas occupies a volume of 1dm³ ;
1000cm³ = 1dm³
120cm³ gives 0.12dm³;
Now;
1dm ³ of gas contains 1 mole of substance at STP
0.12dm³ will contain 0.12mole of nitrogen gas at STP
Mass of N₂ gas = number of moles x molar mass of N₂
Molar mass of N₂ = 2(14) = 28g/mol
Mass of N₂ = 0.12 x 28 = 3.36g
1 mole of a substance contains 6.02 x 10²³ molecules
0.12 mole of N₂ will contain 0.12 x 6.02 x 10²³ = 7.22 x 10²²molecules

what is the amount of matter in an object.
A mass
B volume
C Density
Answer:
Option A
Explanation:
The answer is "mass" or option A. It's not option B because volume is the amount of space in a object which is not what the question is asking for. It's also not option C because density goes hand in hand with volume measuring how much space a object takes up, and also density is mass per volume. Leaving only option A, therefore it is your answer.
Hope this helps.

What mass of sodium hydroxide is needed to make 0.500 L of 2.50 M NaOH ?
Answer:
50 g NaOH
General Formulas and Concepts:
Chemistry - Solutions
Reading a Periodic TableUsing Dimensional AnalysisMolarity = moles of solute / liters of solutionExplanation:
Step 1: Define
0.500 L
2.50 M NaOH
x moles of solute
Step 2: Define conversions
Molar Mass of Na - 22.99 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of H - 1.01 g/mol
Molar Mass of NaOH - 22.99 + 16.00 + 1.01 = 40 g/mol
Step 3: Find moles of solute
2.50 M NaOH = x moles NaOH / 0.500 L
x = 1.25 moles NaOH
Step 4: Convert

what is magnesium? why does your body need it? how much do you need (per day)? What happens if you have too much or too little of it? Which foods do you find in it? What are some facts about magnesium?
Magnesium is a nutrient that the body needs to stay healthy. if you dont get enough magnesium in your body then you could get magnesium deficiency. Symptoms of magnesium deficiency include loss of appetite, nausea, vomiting, fatigue, and weakness. Extreme magnesium deficiency can cause numbness, tingling, muscle cramps, seizures, personality changes, and an abnormal heart rhythm. The RDA for magnesium is 310–420 mg for adults depending on age and gender. Sources of magnesium are greens, nuts, seeds, dry beans, whole grains and low-fat dairy products.
random facts:
A magnesium ion is present in the chlorophyll molecule of every living green plant.
Magnesium is critically important for the human metabolic system's functioning.

Answer:
diffusion is the movement of gases from a higher concentration area to a lower concentration area
osmosis is the movement of water molecules from a higher concentration area to a lower concentration area

Pure water boils at 100°C.
What happens to the water particles when water boils?
A They gain energy and move further apart.
B They gain energy and stay close together.
CThey lose energy and move further apart.
DThey lose energy and stay close together.
choose one answer correctly!
The boiling of pure water has been resulted in the particles gaining energy and moving away from each other. Thus, option A is correct.
The boiling can be described as the conversion of the liquid state to the gaseous state. The molecules in the gaseous space are apart from each other and have no fixed shape.
The pure water has been transferred to the gaseous state at the temperature of 100 degrees celsius. The boiling has been introduced with the addition of the energy.
The water molecules gain energy and start to vibrate. The vibrations have resulted in the change in the change in phase of the liquid with evaporation.
Thus, when pure water boils, the water particles gain energy and move away from each other. Thus option A is correct.
