I think the answer is D. Contains nitrogen bases hope it helps.
Hello There!
A chemical reaction is when one or more molecules combine and rearrange to create one or more molecules or substances.
Answer:That all noble gases will have 8 valence electrons which makes a atom stable
Explanation:
Answer: The temperature goes up.2.The piston doesn't move in and out.3.Heat flows out.4. Amount of heat evolved is +285 kj/mol
Explanation:
The temperature in the water bath will rise because heat being evolved is absorbed it.Based on principle of constant pressure, the piston doesn't move in and out.Since the reaction is a combination reaction, heat will be evolved.
Steps for Determining an Empirical Formula
<span>1. Begin
with the number of grams of each element, given in the problem.2. Convert
the mass of each element to moles by means of the molar mass from the
periodic table.
3. Divide
each mole value by the smallest number of moles computed.
<span>4. Round
to the nearest whole number.</span>
