Answer:

Elements are types of atoms that have a unique number of protons. In fact, from left to right, the periodic table is arranged by the number of protons that each element contains. oms make up matter. An atom is the smallest unit of matter that retains all of the chemical properties of an element.

If a bullet travels at 407.0 m/s, what is its speed in miles per hour? Number click to edit mi/h For the same bullet travelling
kaheart [24]

Answer : The speed in miles per hour is 22 mile/hr.

The speed in yard per min is 26617.8 yard/min

Explanation :

The conversion used for meters to miles is:

1m=100cm\times \frac{1in}{2.54cm}\times \frac{1ft}{12in}\times \frac{1mile}{5280ft}

The conversion used for second to hour is:

1s=\frac{1}{60}min\times \frac{1hr}{60min}

The conversion used for meter per second to mile per hour is:

1\frac{m}{s}=\frac{100cm\times \frac{1in}{2.54cm}\times \frac{1ft}{12in}\times \frac{1mile}{5280ft}}{\frac{1}{60}min\times \frac{1hr}{60min}}

As we are given the speed of 407.0 meter per second. Now we have to determine the speed in miles per hour.

1m/s=2.2mile/hr

So, 407.0m/s=\frac{2.2mile/hr}{1m/s}\times 407.0m/s=895.4mile/hr

Therefore, the speed in miles per hour is 22 mile/hr.

The conversion used for meter to yard

1m = 1.09 yard

The conversion used for second to hour is:

1s=\frac{1}{60}min

The conversion used for meter per second to mile per hour is:

1m/s=\frac{1.09yard}{frac{1}{60min}}

1m/s=65.4yard/min

As we are given the speed of 407.0 meter per second. Now we have to determine the speed in yards per min

1m/s=65.4yard/min

So, 407.0m/s=\frac{65.4yard/min}{1m/s}\times 407.0m/s=26617.8yard/min

Therefore, the speed in yard per min is 26617.8 yard/min

What are the answers to these?
antiseptic1488 [7]

Answer: 1. AgF + CaCl2 = AgCl + CaF2

2. C2H4 +O2 = CO2 +H2O

3. K2S = K+S

4. O2 + Mg = MgO

5. Mg + AlBr3 = MgBr2 + Al

6.C2H6O + O2= CO2 + H2O

7.Li2SO4 + MgCl2= Li2SO4 + MgCl2

8.HCl + Zn= H2 + ZnCl2

Explanation:

Balance the equation

Write down your given equation.

Write down the number of atoms per each element that you have on each side of the equation.

Always leave hydrogen and oxygen for last.

If you have more than one element left to balance:

Add a coefficient to the single carbon atom on the right of the equation to balance it with the 3 carbon atoms on the left of the equation.

Balance the hydrogen atoms next.

Balance the oxygen atoms.

What is the purpose of galvanization?​
frutty [35]
Galvanizing protects from rust in a number of ways: It forms a barrier that prevents corrosive substances from reaching the underlying steel or iron. The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.

Which properties determines the element that an atom Is?
balandron [24]

Answer:

The answer would be C. Number of protons in the atom.

Explanation:

On the periodic table, you see the element, with a big number at top, and a small number below the element name/abbreviation.

The big number is the amount of protons of the atom, which define each atom. The smaller number represents the atomic mass of the atom.
