Answer:

methylhexane.

Explanation:

Because thats the answer.

Answer:

=71.439911 u

Explanation:

We know that 1 mass of hydrogen atom = 1.00784 u

If it's measured at 72u: 72/1.00784=71.439911 u

Mass of 1 mol hydrogen atoms =1.00784u

Total mass in 72u

⇒ 0.018

-use pH=-log[H3O+]

-solve for H3O+

Answer:

Yes, at high temperature and pressure (1011 kpa), diamond can change directly (sublime) into gaseous form.

Diamond is a solid form of the carbon element with its atoms arranged in a crystal structure called diamond cubic.

Diamond has some interesting properties, which is written below;

A diamond interacts with oxygen in the air and disappears to form carbon dioxide.

Thus, at high temperature and pressure (1011 kpa), diamond can change directly (sublime) into gaseous form.

Dust clouds that moved to the east coast of the united states were composed mostly of silt and clay particles due to constant ploughing during drought.

This is defined as dry period in the climate due to insufficient rainfall in the area at a given time.

The drought led to the soil being constantly ploughed thereby loosening and changing the soil type which is susceptible to wind erosion.

Molarity is the ratio of the moles and the volume. The mass of 2.6 M sodium phosphate solution is 2131.22 gms.

Mass is the product of the moles and the molar mass of the substance. It is given as,

Mass = Moles × Molar mass

The moles from molar concentration is used to calculate mass as:

Mass = Molarity × volume × molar mass

= 2.6 × 5.0 × 163.94

= 2131.22 gms

Therefore, 2131.22 gms is the mass of sodium phosphate.
