Answer:
A) They are all acidic.
Explanation:
All 3 of those have acidic qualities in the drink.
The answer is B.) Some plates move toward each other, while others move away from or alongside each other.
Answer:
The answer is
<h2>0.4 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of wood = 120 g
volume = 300 cm³
So the density of the wood is

We have the final answer as
<h3>0.4 g/cm³</h3>
Hope this helps you
Answer:
The temperature of the gas is 876.69 Kelvin
Explanation:
Ideal gases are a simplification of real gases that is done to study them more easily. It is considered to be formed by point particles, do not interact with each other and move randomly. It is also considered that the molecules of an ideal gas, in themselves, do not occupy any volume.
The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:
P*V = n*R*T
where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas.
In this case:
- P= 470 mmHg
- V= 570 mL= 0.570 L
- n= 0.216 g= 0.0049 moles (being the molar mass of carbon dioxide is 44 g/mole)
- R= 62.36367

Replacing:
470 mmHg*0.570 L= 0.0049 moles* 62.36367
*T
Solving:

T= 876.69 K
<em><u>The temperature of the gas is 876.69 Kelvin</u></em>
