Answer:
The problem tells you that
6 g
of hydrogen gas,
H
2
, react with an unknown mass of oxygen gas,
O
2
, to form
54 g
of water.
As you know, the law of mass conservation tells you that the in a chemical reaction the total mass of the reactants must be equal to the total mass of the products.
In your case, this can be written as
total mass of reactants
m
H
2
+
m
O
2
=
mass of product
m
H
2
O
This means that the reaction must have consumed
m
O
2
=
m
H
2
O
−
m
H
2
m
O
2
=
54 g
−
6 g
=
48 g O
2

The correct answer is April 10th.
The breaking strengths of cables produced by a certain manufacturer have a standard deviation of pounds. a random sample of newly manufactured cables has a mean breaking strength of pounds are 1821.9.
<h3>
What are the cables?</h3>
The cables are the wires that provide the connection.
- Round your solutions to 1 decimal place pattern imply = 1800 fashionable error = zs = 2.576[85/sqrt(100)] = 0.2576*eighty five = 21.896
- 99% CI: 1800-21.896 < u < 1821.896
- 99% CI: 1778.1 < u < 1821.9.

The confidence interval and the interpretation of it is; CI = (0.34, 0.40) which means that the 95% confidence interval for the proportion of all people in the United States who would indicate that their favorite sport to watch on television is American football is (0.34, 0.40).
<h3>What is the confidence interval?</h3>
We are given;
Sample proportion; p = 37% = 0.37
Sample size; n = 1000
The confidence interval for the population proportion, is given by the formula;
CI = p ± z√[(p(1 - p)/n)]
z for Confidence level of 95% is z = 1.96.
Thus;
CI = 0.37 ± 1.96√[(0.37(1 - 0.37)/1000)]
CI = 0.37 ± 0.03
CI = (0.34, 0.40)
Thus, the 95% confidence interval for the proportion of all people in the United States who would indicate that their favorite sport to watch on television is American football is (0.34, 0.40).
