Ordered: 0.3 gm. Available: 300 mg/tablet. How many tablets should be given?
dimulka [17.4K]

Answer:

1 tablet

Explanation:

Assuming that gm stands for gram:

Put everything in one unit, 0.3 g = 300 mg.

And given that each tablet is 300 mg:

mass/amount = 300mg / 1 tablet

300mg / X amount = 300mg / 1 tablet

(300mg/300mg) tablet = X = 1 tablet

So it is 1 tablet you need.

HELP PLEASE! :( 
BabaBlast [244]

Answer:

Part 1: W = 116 Y = 163

Part 2: Since 232 is the mailing point of 2 kg then you would divide 232 by 2 to get the melting point for 1 kg, the same with Y.

When the following equation is balanced using the smallest possible integers, what is the number in front of the substance in bo
weeeeeb [17]

The balanced equation :

8Al + 3Fe₃O₄→ 4Al₂O₃ + 9Fe

You just have to look for which element is in bold because the question is not clear

<h3>Further explanation</h3>

Equalization of chemical reaction equations can be done using variables. Steps in equalizing the reaction equation:

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c etc.

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index between reactant and product

3. Select the coefficient of the substance with the most complex chemical formula equal to 1

Reaction

Al + Fe₃O₄→ Al₂O₃ + Fe

give a coefficient

aAl + Fe₃O₄→ bAl₂O₃ + cFe

O, left=4, right=3b⇒3b=4⇒b=4/3

Al, left=a, right=2b⇒a=2b⇒a=2.4/3⇒a=8/3

Fe, left=3, right=c⇒c=3

The equation becomes :

8/3Al + Fe₃O₄→ 4/3Al₂O₃ + 3Fe x3

8Al + 3Fe₃O₄→ 4Al₂O₃ + 9Fe
