Which factors cause a rising tide
mestny [16]

High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

How many grams of carbon dioxide are produced from the combustion of 1.3 moles of acetylene
Karo-lina-s [1.5K]
Complete combustion of acetylene generated carbon dioxide and water. This can be represent by following reaction

2C2H2   +    5O2     →      4CO2     +     2H2O
(2 mole)                            (4 mole)

From the above balanced reaction, it can be seen that 2 mole of acetylene on complete combustion generates 4 moles of carbon dioxide
i.e. 2 mole of C2H2 ≡ 4 mole of CO2
∴ 1.3 mole of C2H2 ≡ (4 X 1.3)/2 = 2.6 mole of CO2

Now, 1 mole of CO2 = 44 g
∴ 2.6 mole of CO2 = (44 X 2.6) = 114.4 g

Thus,  <span>114.4 grams of carbon dioxide are produced from the combustion of 1.3 moles of acetylene</span>

Laura is supplied with 5 bolts (B) and 12 nuts (N). She attached the nuts to the bolts in a 2:1 ratio (N2B). Which of the reacta
Andrews [41]

Answer:

The bolts will run out first, so these will limit how much product can be formed.

(option C is correct)

Explanation:

Step 1: Data given

Number of bolts = 5

Number of nuts = 12

ratio N:B = 2:1

Step 2

Since the ratio N:B is 2:1 we have 2 nuts for each bolt

When we have 2 bolts we have 4 nuts

When we have 3 bolts we have 6 nuts

When we have 4 bolts we have 8 nuts

When we have 5 bolts we have 10 nuts

We don't have more bolts, but there are still 2 nuts left. This means the bolts will run out first, so these will limit how much product can be formed.

(option C is correct)
