How is the process of mitosis essential to the survival of an organism?

ELEN [110]

Answer:

Explanation:

Mitosis is crucial to this process. Mitosis is the reason we can grow, heal wounds, and replace damaged cells. Mitosis is also important in organisms which reproduce asexually: this is the only way that these cells can reproduce. This is the one key process that sustains populations of asexual organisms.Jul 22, 2020

Calculate the number of moles of magnesium, chlorine, and oxygen atoms in 5.90 moles of magnesium perchlorate, Mg(ClO4)2.

Lady bird [3.3K]

Answer:

5.90, 11.8, 47.2

Explanation:

Let’s remove the parentheses and write the formula as MgCl₂O₈.

We see that 1 mol Mg(ClO₄)₂ contains 1 mol Mg atoms, 2 mol Cl atoms, and 8 mol O atoms.

∴ $\text{Moles of Mg atoms} = \text{5.90 mol Mg(ClO}_{4})_{2} \times \frac{\text{1 mol Mg atoms}} {\text{1 mol Mg(ClO}_{4})_{2}} = \text{5.90 mol Mg atoms}$

$\text{Moles of Cl atoms} = \text{5.90 mol Mg(ClO}_{4})_{2} \times \frac{\text{2 mol Cl atoms}} {\text{1 mol Mg(ClO}_{4})_{2}} = \text{11.8 mol Cl atoms}$

$\text{Moles of O atoms} = \text{5.90 mol Mg(ClO}_{4})_{2} \times \frac{\text{8 mol O atoms}} {\text{1 mol Mg(ClO}_{4})_{2}} = \text{47.2 mol O atoms}$

∴ Mg, Cl, O = 5.90, 11.8, 47.2

10 grams CH10 + excess O2 → ? grams CO2 + H2O

Contact [7]

Answer:

20 gm CO2

Explanation:

CH10 mole weight = ~ 22 gm

each 22 gm CH10 produces 44 gm CO2

44 / 22 = x / 10 = 20 gm

i. What is the Lewis structure for CH3CHCHOH? (If resonance is present, draw only one structure.)ii. What is the total number of

Minchanka [31]

Answer:

i: answer is in attachment.

ii: 24 valance electron in overall structure

iii: carbon having positive charge while oxygen having negative

iv: a bond angle of approximately 104.5 degrees.

v: CH3 having sp3 hybridization and both CH having sp2 hybridization

vi: yes. resonance occur between CH=CH and oxygen.

Explanation:

iii: oxygen is electronegative so attraction of electrons occur at oxygen results in negative charge.

iv: a bond angle is about 104.5 degrees because the oxygen has 2 lone pairs and 2 bond pairs of electrons so lone pairs repulsion occur more than bonding pairs that's why the angle is less than that of an atom with tetrahedral or pyramidal geometry.
