Answer:
1) CO₂
2) 0.2551 g
Explanation:
The balanced reactions are:
CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂
MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂
1) The gas produced is CO₂.
2) Calculate mass of CaCO₃:
(0.5236 g) (0.4230) = 0.2215 g CaCO₃
Convert to moles:
(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃
Find moles of CaCO₃:
(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂
Convert to mass:
(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂
Calculate mass of MgCO₃:
(0.5236 g) (0.5770) = 0.3021 g MgCO₃
Convert to moles:
(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃
Find moles of MgCO₃:
(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂
Convert to mass:
(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂
Total mass of CO₂:
0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂
A ribosome is the part of a cell is used by a virus to produce its protective
protein coat.
Virus produces a protective protein coat known as capsids which serves as
a means of protection for the organism. The capsids are produced through
the organelle known as ribosome.,
The ribosome acts as a site for protein synthesis in organisms and the
capsids being made up of protein means the ribosome was used to
produce its protective protein coat.

Adenosine triphosphate (also called ATP) is used by the cell as fuel to
pump sodium out of the cell during the process of active transport. It
carries energy to the areas of the body where it is needed. It is
necessary for many of the cell's functions and is an important part of
metabolism.
Answer:
how are genes expressed for a particular trait?
Genes are expressed in two ways which could be either genotype or phenotype
genotype reflects the dominancy or recessives of a particular trait over another while phenotype entails the physical expression of such trait which could be height, color of skin among others
e.g
If P is purple while p is white
PP x Pp= PP, Pp, PP. Pp these are the genotype produced from the crossing of two parents which results into 2 homozygous gene and 2 heterozygous gene without any recessive gene
while the phenotype shows that all the offspring are Purple
Explanation:
One of the side effects of smoking is the damage of cilia in the trachea
which allows particles to entre the lungs. Smoking destroys the cilia
which are key in keeping particles from getting down into your lungs so
every time a person smokes more and more cilia are destroyed.
