Muscles cells are called?
evablogger [386]

Answer:

They are called Myocyte.

Explanation:

A myocyte is said to be the type of cells that is found in muscle tissue. They are structurally long and also posses tubular cells that inhibits develop from myoblasts to form myogenesis process which are muscles.

Within a skeletal muscle fibre, there are many myocytes. arranged parallel to one another which gives the fibre a striated appearance. They are contractile parts of the muscle fibre.

Also, different forms of these myocytes has different qualities in our body muscles found in the cardiac, skeletal, and smooth muscle cells.

4. Calculation of theoretical yield and percent yield You balanced this reaction earlier: Mg(s) + HCl (aq) H2 (g) + MgCl2 (aq) Y
erik [133]

Answer:

Mg(s) +<em> 2</em> HCl (aq) →  H₂(g) + MgCl₂

0.415g of H₂(g) <em>-Assuming mass of Mg(s) = 10.0g-</em>

Explanation:

Balancing the reaction:

Mg(s) + HCl (aq) →  H₂(g) + MgCl₂

There are in products two atoms of H and Cl, the balancing equation is:

Mg(s) +<em> 2</em> HCl (aq) →  H₂(g) + MgCl₂

<em>Assuming you add 10g of Mg(s) -Limiting reactant-</em>

<em />

10g of Mg are (Atomic mass: 24.305g/mol):

10g × (1 mol / 24.305g) = <em>0.411 moles of Mg</em>

<em>-Theoretical yield is the amount of product you would have after a chemical reaction occurs completely-</em>

Assuming theoretical yield, as 1 mole of Mg(s) produce 1 mole of H₂(g), theoretical yield of H₂(g) is 0.411moles H₂(g). In grams:

0.411mol H₂(g) × (1.01g / mol) = <em>0.415g of H₂(g)</em>
