2023年8月10日 · In 4H2O, there are 8 oxygen atoms (4 molecules x 2 oxygen atoms per molecule). So, in total, you've got 14 oxygen atoms floating around in that equation. Hope that clears things up for ya!

2018年5月1日 · Hydrated chromium(III) phosphate or chromium(III) phosphate tetrahydrate. We first look at the first part of the chemical formula, which is simply CrPO_4. Notice that this molecule has a phosphate (PO_4^(3-)) ion bonded to a chromium ion, which we will find out its charge. Let x be the charge of the chromium ion. So, we get: x+(-3)=0 x-3=0 x=3 So, chromium is in its +3 oxidation state, and ...

2025年2月26日 · The formula 4H2O means there are 4 water molecules (H2O) present. Each water molecule consists of 2 hydrogen atoms and 1 oxygen atom. Therefore, in 4H2O there are 8 hydrogen atoms and 4 oxygen ...

2024年6月12日 · Now back to 4H2O. The coefficient 4 tells you there are four molecules of H2O. Therefore there are eight H(hydrogen) atoms and four O(oxygen) atoms. Wiki User. ∙ 12y ago. This answer is:

The formula 4H2O means there are 4 water molecules (H2O) present. Each water molecule consists of 2 hydrogen atoms and 1 oxygen atom. Therefore, in 4H2O there are 8 hydrogen atoms and 4 oxygen ...

2018年3月7日 · C_3H_8 + 5O_2 -> 3CO_2 + 4H_2O We have: C_3H_8 + O_2 -> CO_2 + H_2O I would always start by balancing the elements that only occur once on each side. In this case it's carbon. We also notice that as it now stands we have an odd number of oxygen molecules on the right and an even number on the left, which won't work. We can fix this by multiplying the water by an even number. C_3H_8 + O_2 -> CO ...

A mole ratio is the ratio of the amounts in moles of any two compounds involved in a chemical reaction. It details how much of each compound is necessary to create a specific product.

2018年4月25日 · 95.3g C_3H_8 First, check to ensure that the equation is balanced (it is). Then calculate the required moles of product water for a mass of 156 grams. Then use the ratio of moles of product H_2O to reactant C_3H_8 to find the moles of propane required. Finally, use that value with the molecular weight of propane (44) to find the mass of propane required. 156/18 = 8.67 moles H_2O (1 "mol" C_3H ...

2014年9月18日 · The percent yield is 74.4 %. Fe₃O₄ + 4H₂ → 3Fe + 4H₂O First, calculate the theoretical yield of H₂O.
