Answer:
When a candle burns, the hydrogen and carbon from the wax combine with the oxygen in the air to become carbon dioxide and water vapor. Most of the matter in the candle ends up as these two gases.
Answer:
<h2>15 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

f is the force
m is the mass
From the question we have

We have the final answer as
<h3>15 m/s²</h3>
Hope this helps you
Answer: 1and 4
Explanation: iron is an element not an alloy. An ionic lattice is not bonded covalently.
The percent composition of the compound.
A O-18.18%, N-21.21%, H-60.60%
<h3>Further explanation</h3>
Given
6.00 grams of oxygen,
7.00 grams of nitrogen,
20.00 grams of hydrogen.
Required
The percent composition
Solution
Total mass :
= mass of O + mass of N + mass of H
= 6 + 7 + 20
= 33 g
% O = 6/33 x 100%= 18.18%
% N = 7/33 x 100%=21.21%
% H = 20/33 x 100% = 60.6 %
<span>I believe the answer is B)Diuretic therapy
</span>
The patient has alkalosis(pH 7.49), increased respiratory rate (20/min) and decreased carbon dioxide level(<span>pCO2 30). These findings point to respiratory alkalosis.
The reason for increased respiratory rate probably because of heart failure that is shown by the decreased </span>cardiac index, pO2, <span>crackles, and wheezes. The treatment for congestive heart failure is to decrease the preload and blood pressure by giving a strong diuretic like furosemide.</span>
