Answer: 1 mol of carbonate to 2 mol of acid
Explanation:
To calculate the number of moles for given molarity, we use the equation:
a) 
b) 
Thus the mole ratio of carbonate to acid is = 
<span>The molar volume of a gas at STP, in liters, is 22.4
you then multiply 22.4 by 2 to get the answer to the next question:
</span><span>
You can use the molar volume to convert 2 mol of any gas to 44.8 L
</span>
<span>You can also use the molar volume to convert 11.2 L of any gas to 0.500 mol.
</span>
Avogadro’s law tells you that 1.2 L of O2(g) and 1.2 L of NO2(g<span>) are the same </span><span>numbers of moles of gas.</span>

Answer:</h3>
0.387 J/g°C
<h3>
Explanation:</h3>
- To calculate the amount of heat absorbed or released by a substance we need to know its mass, change in temperature and its specific heat capacity.
- Then to get quantity of heat absorbed or lost we multiply mass by specific heat capacity and change in temperature.
- That is, Q = mcΔT
in our question we are given;
Mass of copper, m as 95.4 g
Initial temperature = 25 °C
Final temperature = 48 °C
Thus, change in temperature, ΔT = 23°C
Quantity of heat absorbed, Q as 849 J
We are required to calculate the specific heat capacity of copper
Rearranging the formula we get
c = Q ÷ mΔT
Therefore,
Specific heat capacity, c = 849 J ÷ (95.4 g × 23°C)
= 0.3869 J/g°C
= 0.387 J/g°C
Therefore, the specific heat capacity of copper is 0.387 J/g°C
Answer:
Hi there!
The correct answer is 2.29 x 
molecules
Explanation:
To convert from the moles to molecules:
1 mole = 6.022 x 10²³ molecules
so basically you multiply 3.8 by 6.022 x 10²³
and you get: 2.29 x
