(58 g)/ (4L) reduce units to one
katen-ka-za [31]

Answer is 14.5 g L⁻¹.

<em>Explanation;</em>

Here, the question says reduce the units as one.

The presented units are g/L. To reduce the units to one, what we can do is take L to the upper side.

This can be done according to the rules of indices;

1 / aˣ = a⁻ˣ

Like that, we can write 1 / L as L⁻¹.

Hence, the reduced unit is g L⁻¹.

But remember to keep a space between when writing two different units.

Actually, this is an unit for density.

Give two different conditions under which long chain hydrocarbons may be cracked.​
sammy [17]
In thermal cracking, high temperatures (typically in the range of 450°C to 750°C) and pressures (up to about 70 atmospheres) are used to break the large hydrocarbons into smaller ones. Thermal cracking gives mixtures of products containing high proportions of hydrocarbons with double bonds - alkenes.

Which atom or ion is the largest? A.K B. K+ C. Ca D. Ca2+ E. Li
lapo4ka [179]

Consequently, the ion with the greatest nuclear charge (Al 3 +) is the smallest, and the ion with the smallest nuclear charge (N 3−) is the largest. The neon atom in this isoelectronic series is not listed in Table 2.8.3, because neon forms no covalent or ionic compounds and hence its radius is difficult to measure.

With all his gear, Neil Armstrong weighed 360 pounds on Earth. When he landed on the Moon, he weighed 60 pounds. Why?
lyudmila [28]

C. The gravity on the Moon is less than the gravity on Earth.

Explanation:

The weight of Neil Armstrong changed because the gravity on the Moon is less than the gravity on earth. We can infer that the gravity on moon is one-sixth the gravity earth.

  • Mass of Armstrong on earth and moon is the same. Mass is the quantity of matter contained in a substance. Since he has the same quantity of matter on earth and moon, his mass will be the same.

Weight is a function of mass and gravity on a body.

Since his weight reduced, we can infer that the gravity on the moon is lesser:

        Weight = mass x gravity.
