Decide which element probably forms a compound with oxygen that has a chemical formula most and least similar to the chemical fo

rmula of the compound formed by oxygen and cesium.

mafiozo [28]2 years ago

Answer:

Most similar   -----  Lithium

Least similar   ----  Nitrogen

Explanation:

Cesium is an element on the periodic with the atomic number 133. It lies in group 1 (i.e., the alkali metals) and period 6 on the periodic table. The oxidation state of group 1 metals is +1. Cesium forms an oxide with oxygen as  Cs_2O.

The most similar compound to this chemical compound is Lithium because Lithium happens to be in the same group one metal with Cesium and forms the compound Li_2O with the oxygen

The least similar compound nitrogen due to fact that it is an oxide that is covalent in nature and lies between-group 3 -17  to form an NO_2 with oxygen.

Which statement correctly explains how magnesium and chlorine combine to form magnesium chloride?
AysviL [449]
You did not include the statements but since magnesium chloride is ionic substance that we know that magnesium and chlorine formed an ionic bond.  Therefore your statement most likely will talk about how one magnesium atom gave up 2 electrons while two chlorine atoms took 1 electron.  The reaction looks like Mg+2Cl⇒MgCl₂.  
I hope this helps.  Let me know in the comments if anything is unclear.

If the density of a 45.0 cm3 block of wood is 0.65 g/ml what is the mass of the wood?
wlad13 [49]

Answer:

\boxed {\tt mass=29.25 \ grams}

Explanation:

The density formula is mass over volume.

d=\frac{m}{v}

Rearrange the formula for the mass, m. Multiply both sides of the formula by v.

d*v=\frac{m}{v}*v

d*v=m

Mass can be found by multiplying the density and volume. The density is 0.65 grams per milliliter and the volume is 45.0 cubic centimeters.

  • A cubic centimeter is equal to a milliliter.
  • Therefore, 45 cubic centimeters also equals 45 milliliters.

d= 0.65 \ g/mL\\v= 45 \ mL

Substitute the values into the formula.

0.65 \ g/mL * 45 \ mL=m

Multiply. Note the milliliters, or mL will cancel out.

0.65 \ g * 45=m

29.25 \ g=m

The mass of the wood is 29.25 grams.

A car with a mass of 1,200 kilograms is moving around a circular curve at a uniform velocity of 20 meters per second. The centri
Helga [31]
The answer is 80 m.

Centripetal force (F) is a force that makes body move around a circular curve. The unit of force is N (N = kg * m/s²).
It can be represented as:
F= \frac{m* v^{2} }{r}
where:
m - mass
v - velocity
r - radius of the curve

We have:
m = 1,200 kg
V = 20 m/s
F = 6,000 N = 6,000 kg * m/s²

We need radius of the curve:
r = ?

So, if <span>F= \frac{m* v^{2} }{r}, then:
</span>    r= \frac{3* v^{2} }{F}
⇒ r =  \frac{1200 kg * (20m/s)^{2} }{6000 kg*m/s^{2} }
⇒ r= \frac{1200*400*kg*m^{2}*s^{2}  }{6000kg*m/s^{2} }
⇒ r= \frac{480,000m}{6000}
⇒ r=80m
