What is the name of the compound with the formula Na2CrO4?
The compound with the formula Na2CrO4 is called sodium chromate. It is a yellow crystalline solid that is commonly used in industrial processes such as producing pigments and as a corrosion inhibitor.
What is Na2CrO4 3H2O?
Sodium chromate, a yellow crystalline solid, is the chemical compound Na2CrO4. Its hydrated form, Na2CrO4·3H2O, contains three molecules of water per molecule of sodium chromate. This compound is water-soluble and is commonly used in laboratory applications.
How many moles of Na2Cro4 are contained in 74.3 grams of the compound?
Oh, dude, let's break it down. So, first off, you gotta calculate the molar mass of Na2CrO4, which is around 205.99 g/mol. Then, you divide the given mass by the molar mass to find the moles. In this case, 74.3 g / 205.99 g/mol gives you approximately 0.36 moles of Na2CrO4. So, there you have it, like, around 0.36 moles of that stuff in 74.3 grams.
Is Na2CrO4 souble or insoluble in water?
It is soluble but does take a little effort to get it into solution.
What is the oxidation number of Na2CrO4?
The oxidation number of Na in Na2CrO4 is +1 and the oxidation number of O in Na2CrO4 is -2. To find the oxidation number of Cr, we let x be the oxidation number: 2(+1) + x + 4(-2) = 0 x = +6 Therefore, the oxidation number of Cr in Na2CrO4 is +6.

What is the chemical equation for lithium hydroxide sodium chromate?
Na2CrO4 (aq) + 2LiOH (aq) -----> Li2CrO4 (s) + 2NaOH (aq)
What is the formula for sodium chromate?
Na2CrO4
What is the total number of moles of nacl formed with 2 moles of na2cro4 react completely?
If 2 moles of Na2CrO4 react completely, they will form the same number of moles of NaCl. This is because the mole ratio between Na2CrO4 and NaCl is 1:2. Therefore, 2 moles of Na2CrO4 will form 2 moles of NaCl.
How many moles of Na2Cro4 are contaned in 74.3 Grams?
To find the number of moles of Na2CrO4 in 74.3 grams, you need to divide the given mass by the molar mass of Na2CrO4. The molar mass of Na2CrO4 is calculated by adding the atomic masses of all the elements: 2(Na) + Cr + 4(O). Then divide 74.3 grams by the molar mass of Na2CrO4 to get the number of moles.
