Answer:

A, they get their food in the same way.

Explanation:

Some fungi can be toxic or poisonous.

Example: mushrooms. Mushrooms typically are found in forests and meadows/plains.

Some fungi are glowing, brown, and in many forms/shapes.

In conclusion, fungi all get nutrient from the dirt they grew in, forests can be moist which gives fungi excellent places to form, usually around trees, because they can absorb plenty of nutrients from the dirt.

Calculate the ph of the solution upon the addition of 0.015 mol of naoh to the original buffer. express the ph to two decimal pl

tatiyna

You missed a lot of details in your question, so when we have the complete question as the attached picture so, the answer would be:

when we have the value of Ka = 1.8 x 10^-5 so, we can use it to get the Pka value

by using this formula:

Pka = -㏒Ka

= -㏒(1.8 x 10^-5)

= 4.7

now, after we have got the Pka we need now to get moles of NaC2H3O2 and

moles of HC2H3O2:

when moles of NaOH = 0.015 moles

when moles NaC2H3O2 after adding NaOH

= initial mol NaC2H3O2 + mol NaOH
∴moles NaC2H3O2 = 0.1 + 0.015 = 0.115 moles

and moles HC2H3O2 after adding NaOH

= initial mol HC2H3O2 - mol NaOH

∴ moles HC2H3O2 = 0.1 - 0.015 = 0.085 moles

so, when we have moles [HC2H3O2] &[NaC2H3O2] so we can substitution its values in [A] &[HA] :

by using H-H equation we can get the PH:

when PH = Pka + ㏒[A]/[HA]

PH = 4.7 + ㏒0.115/0.085

= 4.8

The fatty acids in the tail of a phospholipid molecule are _____. nonpolar and hydrophobic

andreyandreev [35.5K]

Nonpolar and hydrophobic

Phospholipid molecules have a polar and hydrophillic head, which consists of glycerol and phosphate ions. In a plasma membrane, this head points towards the hydrophillic environment outside of the cell. The tails, on the other hand, are hydrophobic and nonpolar, which means they do not allow water to pass through them.

Find the Molarity of a solution containing 2.5 moles of solute in 15000 milliliters.

garri49 [273]

Molarity is defined by the number of moles of a substance dissolved in a number of liters in solution. 15,000 milliliters is equal to 15 liters, so

2.5/15 = 0.1666... M

The molarity of this solution would be 0.167.

You have 56.8 mL of a gas collected at 664 mmHg and 135 K. What volume will it occupy at 632 mmHg and 196 K? *

tensa zangetsu [6.8K]

Answer:

86.6 mL

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 56.8 mL

Initial pressure (P₁) = 664 mmHg

Initial temperature (T₁) = 135 K

Final pressure (P₂) = 632 mmHg

Final temperature (T₂) = 196 K

Final volume (V₂) =?

The final volume of the gas can be obtained as follow:

P₁V₁/T₁ = P₂V₂/T₂

664 × 56.8 / 135 = 632 × V₂ / 196

Cross multiply

135 × 632 × V₂ = 664 × 56.8 × 196

85320 × V₂ = 7392179.2

Divide both side by 85320

V₂ = 7392179.2 / 85320

V₂ = 86.6 mL

Therefore, the final volume of the gas is 86.6 mL

what is the balanced equation for the reaction of solid magnesium metal with oxygen gas to produce solid magnesium oxide

GaryK [48]

Answer:

2Mg + O₂ ⟶ 2MgO

Explanation:

Step 1. Start with the most complicated-looking formula (O₂?).

Put a 1 in front of it.

Mg + 1O₂ ⟶ MgO

Step 2. Balance O.

We have fixed 2 O on the left. We need 2O on the right. Put a 2 in front of MgO.

Mg + 1O₂ ⟶ 2MgO

Step 3. Balance Mg.

We have fixed 2 Mg on the right-hand side. We need 2 Mg atoms on the left. Put a 2 in front of Mg.

2Mg + 1O₂ ⟶ 2MgO

Every formula now has a coefficient. The equation should be balanced. Let’s check.

Atom On the left On the right

Mg 2 2

O 2 2

All atoms are balanced.

The balanced equation is

2Mg + O₂ ⟶ 2MgO
