From the image shown, the uncertainty in the weighing balance extends to the hundredth place.

<h3>What is a balance?</h3>

A balance is any device that is used for measuring the mass or weight of an object. The balance is a necessary instrument in every laboratory.

Looking at the image shown, the following are true;

  • the uncertainty is in the hundredth place.
  • a mass that falls between 1 gram and 9 grams measured on this balance will always have 3 significant figures.

Write a balanced equation for the decomposition reaction described, using the smallest possible integer coefficients. When ammon
MAXImum [283]

Answer:

NH₄Cl  ------> NH₃  +  HCl

Explanation:

Ammonium Chloride =(NH₄Cl

Ammonia = NH₃

Hydrochloric Acid = HCl

NH₄Cl  ------> NH₃  +  HCl

In decomposition reaction, the reactant is breaking down into smaller parts. In this case, all of the coefficients are 1. The reaction is already balanced.

What is the slope of the line?
pychu [463]

Answer:

The slope of the line is -\frac{10}{7}.

Explanation:

The slope of the line (m) is the change in dependent variable (y) divided by the change in independent variable (x):

m = \frac{y_{f}-y_{o}}{x_{f}-x_{o}} (1)

If we know that (x_{o}, y_{o}) = (0, 2) and (x_{f}, y_{f}) = (1.4, 0), then the slope of the line is:

m = \frac{0-2}{1.4-0}

m = -\frac{10}{7}

The slope of the line is -\frac{10}{7}.

Which element would mostly have chemical properties similar to that of magnesium (Mg)?
DanielleElmas [232]

The elements of same group are placed in same group as they have similar properties. So Calcium is the element which resembles Mangesium.

Calcium and Magnesium both are alkaline earth metals.

They have similar properties as they have similar outer or valence shell electronic configuration

The general electronic configuration of alkaline earht metal is ns2

The electronic configuration of Mg [atomic number 12] and Ca [atomic number 20] are

[Ne]3s^{2}  and [Ar]4s^{2} respectively.
