Answer:

It's a Ionic compound

Explanation:

To tell if CaO (Calcium oxide) is ionic or covalent (also called molecular) we look at the Periodic Table that and see that Ca is a metal and O is a non-metal. When we have a metal and a non-metal the compound is usually considered ionic.

Because we have a metal and non-metal in CaO there will be a difference in electronegativity between the metal and non-metal. This difference results in an electron(s) being transferred from the metal (lower electronegativity) to the non-metal (higher electronegativity). The results in the metal becoming a postitive ion and the non-metal a negative ion. The two opposite charges are attracted and form the ionic bond between atoms in Calcium oxide.

algol [13]

The control group is the plant without the music because nothing is being done to it. while the experimental group is the plant with music because you are testing it in a different environment (the music).

Vinegar is an aqueous solution of acetic acid, ch3cooh. a 5.00 ml sample of a particular vinegar requires 26.90 ml of 0.175 m na

Fed [463]

The molarity of acetic acid in the vinegar is 0.94 M

<u><em> calculation</em></u>

Step 1: write the balanced equation between CH3COOH + NaOH

that is CH3COOH + NaOH → CH3COONa + H2O

step 2 : find the moles of NaOH

moles =molarity x volume in L

volume in liters = 26.90/1000=0.0269 l

moles = 0.175 mol /L x 0.0269 L =0.0047 moles of NaOH

Step 3: use the mole ratio to find moles of CH3COOH

that is the mole ratio of CH3COOH: NaOH is 1:1 therefore the moles of CH3COOH is =0.0047 moles

Step 4: find the molarity of CH3COOH

molarity = moles/volume in liters

volume in liter = 5.00/1000 =0.005 l

molarity is therefore=0.0047 moles/ 0.005 l = 0.94 M

The efficiency : 95%

<h3>Further explanation</h3>

Efficiency : the ratio between output and input work

In general, the value of the output of a machine is less than the value of the input because of the frictional force in the machine.

The greater the efficiency of the engine, the better the machine

Can be formulated :

$\tt E=\dfrac{W_{out}}{W_{in}}\times 100\%$

w output = 190 J

W input = 200 J

The efficiency :

$\tt E=\dfrac{190}{200}\times 100\%=95\%$

How to tell if a compound is ionic or molecular?

zhenek [66]

<span>When naming compounds, the first thing you need to do is decide if the compound is ionic or molecular. *Ionic compounds will contain both metals and non-metals, or at least one polyatomic ion. *Acids will always include the (aq) symbol beside the formula, and the name will include the word acid.</span>
