Answer:
A rock fragment, in sedimentary geology, is a sand-sized particle or sand grain that is made up of multiple grains that are connected on the grain scale. These can include grains which are sand-sized themselves (a granitic rock fragment), or finer-grained materials (shale fragments). at least thats what i thought u were asking
Explanation:
That would be exothermic. Exothermic reactions are processes that release energy, usually in the form of heat or light. Energy is released because the total energy of the products is less than the total energy of the reactants.
Answer:
12.89 moles
Explanation:
Before we solve the question, we have to balance the equation of the reaction first. The balanced reaction will be:
2 NO + 2 H2→ N2 + 2 H2O
There are 180.5g of N2 produced, the number of produced in moles will be: 180.5g / (28g/mol)= 6.446 moles
The coefficient of H2 is two and the coefficient of N2 is one. Mean that we need two moles of H2 for every one mole of N2 produced. The number of H2 reacted will be: 2/1 * 6.446 moles = 12.89 moles
What is the mass, in grams, of 0.00948\,\text {mol}0.00948mol0, point, 00948, start text, m, o, l, end text of phosphoric acid?
gulaghasi [49]
Answer:
m = 0.929 grams
Explanation:
We have,
Number of moles of phosphoric acid is 0.00948
It is required to find the mass of phosphoric acid.
The number of moles in a given molecule is given by :
m is mass and M is molecular mass
The molecular formula of phosphoric acid is . Its molecular mass is :
So,
So, the mass of phosphoric acid is 0.929 grams.
The PH level of the surface of the water is 9.0
Hope this helps
