Explanation: True, Ammonia is a base
<h3><u>Answer;</u></h3>
C. 352.6 m/s
<h3><u>Explanation;</u></h3>
Velocity of sound is dependent on temperature. An increase in temperature, increases the velocity of sound.
To calculate the velocity of the sound wave, we use this formula:
V = 331 + [0.6*T]; Where V is the velocity and T represents temperature.
When the temperature is 36 degree Celsius, we have
V = 331 + [0.6 * 36]
V = 331 + 21.6 = 352.6
Therefore,
V = 352.6 m/s.
Answer: C. iron oxide
Explanation:
In a chemical reaction , the reactants are written on the left hand side followed by a rightarrow and then products are given on the right side of the arrow.
In the given chemical equation :
Reactants are iron (Fe) and oxygen 
and product is iron oxide 
.
Use the formula for volume. V = lwh. Plug in the numbers for length,
width, and height. Now we have V = 4.0 x 2.0 x 1.0, which is 8.0. So the
volume of the block is 8.0 cm.
