Answer:
Theoretical yield of tungsten produced = 35.6836915592 ≈ 35. 68 g
Explanation:
The chemical equation can be expressed as follows;
WO3 (s) + 3H2(g) → W(s) + 3 H20(g)
Note that the equation is already balanced.
Molecular Mass of WO3= 183.84 + 15.999 × 3 = 183.84 + 47.997 = 231.837 g
From the equation 1 mole of WO3 reacts with 3 mole of hydrogen molecule.
Molecular mass of tungsten(W) = 183.84 g
1 mole of tungsten was produced from the chemical equation.
WO3 (s) + 3H2(g) → W(s) + 3 H20(g)
From the equation,
231. 837 g of WO3 produces 183.84 g of tungsten
45.0 g of WO3 will produce ?
grams of tungsten produced = 183.84 × 45 /231.837
grams of tungsten produced = 8272.8
/231.837
Theoretical yield of tungsten produced = 35.6836915592 ≈ 35. 68 g
Answer:
Traits are the genetically determined characteristics that are passed from parents to their offspring.
Explanation:
Traits refer to the characteristics that are present in an organism. These traits are passed from the parents to their offspring in the process of reproduction. When two organisms i. e. male and female of the same specie mate with each other forming a fertile offspring which has some characteristics of their parents. Sometimes, organism is closely related to their father and sometime more characters are transferred to offspring from mother.
If lactic acid builds up in the body more quickly than it can be removed, acidity levels in bodily fluids — such as blood — spike. lactic acid buildup occurs when there's not enough oxygen in the muscles to break down glucose and glycogen.
I’m sorry I do not know what the answer is. Are you in forensic science? I’m making my 4 year plan, and I put that as one of science classes. If you are in that high school class can you provide any details on that class. If you know the answer to their question and the second spot is full, please comment under my question for them.
