Answer:
Magnesium nitride, which possesses the chemical formula Mg3N2, is an inorganic compound of magnesium and nitrogen. Moles H2O = 75.0 grams / 18.02 g/mol. This reaction is used to prove that air contains nitrogen gas. Which equation would have the same coefficients in the same order as 2CO2 + 3H20 → C2H6O + 3O2?

Add salt to the water
Answer:
Heat the water up!!
Explanation:
I'm hoping this is right? I'm pretty sure it is! Hope you get it right.
What other substance (besides salt) could you sprinkle over ice to affect how fast it melts? Describe how you would test the substance's impact on the melting time of ice. Predict the results of such a test.
Answer:
See explanation
Explanation:
Salt makes ice to melt faster than it usual. Sugar is another substance that influences the melting time of ice.
If i have a sample of pure ice and another sample of ice treated with sugar. I have to maintain the both initially at 0 degrees temperature and have a stop clock to measure the melting time.
I will ultimately notice that the sample of ice treated with sugar will melt faster than the pure sample of ice due to the presence of an impurity.
How does energy play a role in different rock types forming? I had this question another time in my test and it's asking the same thing again.
Answer:
Yes
Explanation:
Yes, there are many energy forces that directly affect the formation of rocks and other substances. The Sun itself provides both energies in the form of heat/radiation and magnetic energy. Heat can get so intense when combined with pressure from being so far underground that it causes rocks to melt and become magma, which combines with other minerals and forms new types of rocks when they cool in the future. Magnetic energy helps push and pull the waves and wind on Earth which ultimately break down rocks into sand over the years.
