Why are scientists using acoustic surveys to learn about rainforest diversity

Answer:

243L of SO2

Explanation:

You'll want to use the Ideal Gas Law for this problem.

First, determine your formula. V=nRT/P

Next, determine your factors.

V = ?

n = 847g

R = 0.0821L.atm/mol.k

T = 313k (40+273)

P = 89.4kPa

Now just plug it in!

847g x 313k / 89.4kPa  x  0.0821L.atm / mol. K

243L of SO2. Hope this helps!

Answer:

The number of animals greatly exceeded the carrying capacity, destroying the food sources and causing the population to decline.  

ALSO

Overpopulation means that there are too many members in the population and that in the end, this will severely hurt their chances for survival.

Explanation:

The statement relates to overpopulation as overpopulation means that there are too many members in the population and that in the end, this will severely hurt their chances for survival.

Overpopulation means an increase in the number of a specific population in a specific place.

Overpopulated species harm other species. It competes for the food and place.

It also decreases the number of species that are its prey.

Thus, the correct option is B.

Explanation: alpha decay or particle consist of two protons and two neutrons hence it is a helium nucleus.

An alpha particle [tex]\binom {4} {2}[/tex]He is produced in alpha decay reactions, while the parent nucleus' atomic number and mass number drop by 2 and 4 correspondingly.

Therefore, the final answer is "Option B".

Answer:

(A) Heat energy

Explanation:

Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Any material or object that allow the conduction (transfer) of electric charge or thermal energy is generally referred to as a conductor. Conductors include metal, steel, aluminum, copper, frying pan, pot, spoon etc.

In this scenario, Energy is added to cool water in a beaker. The energy causes the temperature of the temperature to rise. Thus, the term which best describes the energy is heat energy because the object becomes hotter due to an increase in temperature and heat applied.

Completely turn off equipment like televisions and stereos when you're not using them.

Choose energy-efficient appliances and light bulbs.

Save water.  

Lower your shades or close your curtains on hot days, to keep the house cool and reduce the use of electric fans or air-conditioning.

Let clothes dry naturally.

Keep lids on pans when cooking to conserve energy.

Use rechargeable batteries.

Don’t use “throw away” products like paper plates and napkins, or plastic knives, forks and cups.

Answer:

Do you mean acids?

Due to chemical reaction

Explanation:

Acids are only stored in glass containers because glass containers rarely react with any substance.They dont react with acids and prevent chemical reaction so the acids can be kept. If acids were kept in metal containers it would react .

Answer:

Both roots are imaginary roots.

Explanation:

Consider these things:

If we try to solve x²+1 = 0, notice that we aren't able to solve the equation in Real Number system because there are no negative outputs for quadratic function.

Remember that quadratic function has range greater or equal to the max-min value.

x-axis plane represents the solutions of that equation. If a graph intersects x-axis plane then it has a solution.

While a graph that doesn't have any intersects on x-plane, it means that the equation for that graph doesn't have real solutions but imaginary solutions.

As you may notice some of parabola graph has one intersect, two intersects or none. One intersect is one solution to the equation — Two intersects are two solutions of the equation and lastly, no intersects mean that no real solutions and remain only imaginary solution.

According to molar concentration, 100 ml of 10 M solution is needed to make 1 liter of a 1 M solution.

Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.

The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.

In terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.In case of two solutions, molar concentration is found out by, M₁V₁=M₂V₂.

On substitution in above formula, V₁=1×1/10=0.1 L=100 ml.

Thus, 100 ml  of a 10 M solution is needed to make 1 liter of a 1 M solution.
