Answer:
H₂S + Cl₂ —> S + 2HCl
Explanation:
? + Cl₂ —> S + 2HCl
To balance the equation above, we must recognise what atoms are present in the products.
The products contains S, H and Cl.
Thus, S, H and Cl must also be present in the reactants.
Considering the equation given above, we can see clearly that H and S is missing in the reactants.
H and S together as a compound is expressed as H₂S.
Now, we shall input H₂S into the equation to obtain the complete equation. This is illustrated below:
? + Cl₂ —> S + 2HCl
H₂S + Cl₂ —> S + 2HCl
Next, we shall verify to see if the equation is balanced.
There are 2 atoms of H on both sides of the equation.
There are 2 atoms of Cl on both sides of the equation.
1 atom of S exist on both sides of the equation.
Thus, the equation is balanced.
Answer: 322.56 Kelvin
Explanation:
Use the Ideal Gas Law
R is the gas constant
T is the temperature in Kelvins
P is the pressure in atmospheres
V is the volume in liters
n is the number of moles of gas
First, the mm of mercury need to be converted to atmospheres using the conversion factor 1atm = 760 torr.
Now plug everything in
3,1,3,1
Explanation:
Reaction equation:
HBr + Al(OH)₃ ⇒ H₂O + AlBr₃
To balance an equation we make sure that the same number of atoms appears on both sides of the expression.
HBr + Al(OH)₃ ⇒ H₂O + AlBr₃
Let us a simple mathematical method to solve this problem
aHBr + bAl(OH)₃ ⇒ cH₂O + dAlBr₃
a, b , c and d are the coefficients that will make the equation balanced;
Conserving H; a + 3b = 2c
Br; a = 3d
Al; b = d
O; 3b = c
let us make a = 1
d = 
b =
c = 1
multiply through by 3;
a = 3, b = 1, c= 3 and d = 1

Answer:
grapefruit juice is an acid
Explanation:
A piece of neutral litmus paper turned red in some grapefruit juice. What does this show about the grapefruit juice
with litmus paper remember:
E R
S E
ACID
BLUE
acids turn litmus red, bases turn it blue
all citrus fruits :llemons, lime, grapefruit, oranges, etc are called
CITRUS FRUITS because they contain citric acid
