What would happen if 5 drops of oil was placed into a bottle of water,shaken and allowed to stand for 10 min?

Consider the following balanced equation. SiO2(s)+3C(s)→SiC(s)+2CO(g) Complete the following table, showing the appropriate numb

vlada-n [284]

Answer:

mol(SiO₂) mol(C) mol(SiC) mol(CO)

3 9 3 6

1 3 1 2

13 39 13 26

2.5 7.5 2.5 5.0

1.4 4.2 1.4 2.8

Explanation:

From the balanced equation:

SiO₂(s) + 3C(s) → SiC(s) + 2CO(g),

It is clear that 1.0 mole of SiO₂ reacts with 3.0 moles of C to produce 1.0 mole of SiC and 2.0 moles of CO.

We can complete the table of no. of moles of each component:

1. 9.0 moles of C:

We use the triple amount of C, so we multiply the others by 3.0.

So, it will be 3.0 moles of SiO₂ with 9.0 moles of C that produce 3.0 moles of SiC and 6.0 moles of CO.

2. 1.0 mole of SiO₂:

We use the same amount of SiO₂ as in the balnced equation, so the no. of moles of other components will be the same as in the balanced equation.

So, it will be 1.0 moles of SiO₂ with 3.0 moles of C that produce 1.0 moles of SiC and 2.0 moles of CO.

3. 26.0 moles of CO:

We use the amount of CO higher by 13 times than that in the balanced equation, so we multiply the others by 13.0.

So, it will be 13.0 moles of SiO₂ with 39.0 moles of C that produce 13.0 moles of SiC and 26.0 moles of CO.

4. 7.5 moles of C:

We use the amount of C higher by 2.5 times than that in the balanced equation, so we multiply the others by 2.5.

So, it will be 2.5 moles of SiO₂ with 7.5 moles of C that produce 2.5 moles of SiC and 5.0 moles of CO.

5. 1.4 moles of SiO₂:

We use the amount of SiO₂ higher by 1.4 times than that in the balanced equation, so we multiply the others by 1.4.

So, it will be 1.4 moles of SiO₂ with 4.2 moles of C that produce 1.4 moles of SiC and 2.8 moles of CO.

Britta traveled 1250 km on her road trip and used 209 L of gasoline, filling her tank atan average of 1.14 euros per liter. Pier

icang [17]

Answer:

Britta paid more per kilometer driven

Explanation:

1) Britta:

Distance traveled: 1,250 Km

Gasoline used: 209 liter

Gasoline price: 1.23 euros / liter

Cost per km = total cost of gasoline / distance traveled

Cost per km = gasoline used × gasoline price / distance traveled

Cost per km = 209 liter × 1.14 (euro / liter) / 1,250 km = 0.19 euro / km

2) Pierce:

Distance traveled: 1,405 km

Gasoline used: 175 liter

Gasoline price = 1.23 euros / liter

Cost per km = 175 liter × 1.23 (euro / liter) / 1,405 km = 0.15 euro / km

3) Comparison:

0.19 > 0.15 ⇒ Britta paid more per kilometer driven

What happens to the reactivity of nonmetals within a group from top of the group to the bottom?

andreev551 [17]

As you go down a group, the atoms get bigger. The bigger the atom, the more unstable it is. The more unstable it is, the more reactive the atom will be. So, as you go down a group, the nonmetals will become more reactive.

Answer:

Hi Lovelys!!

Answer down below!!

Explanation:

Answer: Plants need water for photosynthesis in order to make food. Water is needed more for cooling, to maintain body temperature and transport nutrients.

Reason: Plants need water for photosynthesis. Water also helps move nutrients from the soil into the plant. Too little water can cause a plant to wilt or droop. Too much water can cause a plant's roots to rot. Plants are about 80-95% water and need water for multiple reasons as they grow including for photosynthesis, for cooling, and to transport minerals and nutrients from the soil and into the plant.

Hope this helps!! =3

Have a wonderful day, evening, or night!!
