Answer:
4.55 mol of C₂H₂
Explanation:
Let's verify the reaction:
CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂
Ratio is 1:1, so 1 mol of calcium carbide will produce 1 mol of acetylene.
4.55 mol of CaC₂ will make the same amount of C₂H₂
Answer:
No. Because a pure substance, no matter if an element, compound, it can only contain one kind of particle .
Explanation:
Answer:
500kg.
Explanation:
Newton's Second Law relates force, mass and acceleration to one another through the equation:
F = ma
We can rearrange this equation algebraically to solve for mass:
m = F/a
Substituting our known values for the variables, we get:
m = 1500N/3m/s2
So mass of the object is 500kg.
We know it's kg because Newtons (N) are a unit defined as 1 kg/m/s2, so m/s2 cancels out when we divide :)
Answer:
Dominant traits are traits that more likely to be transferred from a parent to an offspring so scientist use this term dominant.
Explanation:
The simplest situation of dominant and recessive alleles is if one allele makes a broken protein. When this happens, the working protein is usually dominant. The broken protein doesn't do anything, so the working protein wins out. ... If both copies of your MC1R gene code for broken proteins, then you'll have red hair.
