Answer:

A. to absorb carbon dioxide from the atmosphere and use it to make sugar

Explanation:

Green plants with the help of their green coloring pigment called chlorophyll helps to absorb sunlight. This sunlight helps in the process Called photosynthesis in which plants manufacture food (sugar) using CO2(Carbon dioxide)and Water to give Oxygen and Sugar. The oxygen is released back into the atmosphere.

how many grams of silver chloride (AgCI) can be produced if you start with 4.62 grams of barium chloride (BaCI2)
UkoKoshka [18]

The chemical equation representing the reaction of silver nitrate with barium chloride:

2AgNO_{3}(aq) + BaCl_{2}(aq)--> 2AgCl (s) + Ba(NO_{3})_{2}(aq)

Given mass of barium chloride = 4.62 g

Moles of BaCl_{2} = 4.62 g BaCl_{2}*\frac{1 mol BaCl_{2}}{208.23 g BaCl_{2}} =   0.0222 mol BaCl_{2}

Moles of AgCl = 0.0222 mol BaCl_{2} * \frac{2 mol AgCl}{1 mol BaCl_{2}} = 0.0444 mol AgCl

Mass of AgCl = 0.0444 mol AgCl * \frac{143.32 g AgCl}{1 mol AgCl} =  6.36 g AgCl

Answer:

1= Magnesium

2 = Option 3 =  1s² 2s² 2p⁶

Explanation:

An electrically neutral atom consist of equal number of protons and electrons.

The answer for 1st q is magnesium because the electronic configuration showed twelve number of electrons. The atomic number of magnesium is twelve that's why this configuration is of Mg.

Mg₁₂ =  1s² 2s² 2p⁶ 3s²

The second answer is option three because has atomic number ten and third electronic configuration have ten electrons.

Ne₁₀ = 1s² 2s² 2p⁶

It is stable electronic configuration. Neon is inert because of this electronic configuration. The outer most shell is completely filled.

Why does the study of science have limitations
oksano4ka [1.4K]

Science doesn't make moral judgments, doesn't make aesthetic judgments, doesn't tell you how to use scientific knowledge, doesn't draw conclusions about supernatural explanations. So that's why I think it has limitations.
