Answer: Diagram C
Explanation:
When a body is under the influence of 2 or more forces, the effect of all forces may be replaced by a unique force (resulting force), with the same result as all original forces.
In case you have different forces with the same direction but different sense, all forces may be substituted by one resulting force, though the module of this resulting force will be equal to the absolute value of the substraction of the modules of the individual forces
For case C, you should check: 8 N (force with right sense) + 4 N (force with right sense) - 4 N (force with left sense) would give us a resulting force of 8 N (with right sense), which will accelerate the body to the right
Answer:
Explanation:
<u>1) Reactants:</u>
The reactants are:
- <em>Molecular chlorine</em>: this is a gas diatomic molecule, i.e. Cl₂ (g)
- <em>Molecular fluorine</em>: this is also a gas diatomic molecule: F₂ (g)
<u>2) Stoichiometric coefficients:</u>
- <em>One volume of Cl₂ react with three volumes of F₂</em> means that the reaction is represented with coefficients 1 for Cl₂ and 3 for F₂. So, the reactant side of the chemical equation is:
Cl₂ (g) + 3F₂ (g) →
<u>3) Product:</u>
- It is said that the reaction yields <em>two volumes of a gaseous product;</em> then, a mass balance indicates that the two volumes must contain 2 parts of Cl and 6 parts of F. So, one volume must contain 1 part of Cl and 3 parts of F. That is easy to see in the complete chemical equation:
Cl₂ (g) + 3F₂ (g) → 2Cl F₃ (g)
As you see, that last equation si balanced: 2 atoms of Cl and 6 atoms of F on each side, and you conclude that the formula of the product is ClF₃.
Explanation:
Because gold is a very unreactive metal and exists as a pure substance (instead of oxides).

Thats called weathering.
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth.
Hope it helps.
Have a nice day noona/hyung!~  ̄▽ ̄❤️
