Why do we have 2 high tides and 2 low tides a day?
Sunny_sXe [5.5K]
Whereas semidiurnal tides are observed at the equator at all times, most locations north or south of the equator experiencetwo unequal high tides and twounequal low tides per tidal day; this is called a mixed tide and the difference in height between successive high (or low) tides iscalled the diurnal inequality.

if 4.12 L of 0.85-M H3PO4 solution is be diluted to a volume of 10.00 L,what is the concentration resulting solution
Alja [10]

Answer:

The concentration resulting solution = 0.350 M

Explanation:

In case of dilution , the following formula can be used -

M₁V₁ = M₂V₂

where ,

M₁ = initial concentration ,

V₁ = initial volume ,

M₂ = final concentration , i.e. , concentration after dilution ,

V₂ = final volume .

from , the question ,

M₁ = 0.85 M

V₁ = 4.12 L

M₂ = ?

V₂ = 10.0 L

Using the above formula , the molarity of the final solution after dilution , can be calculated as ,

M₁V₁ = M₂V₂

0.85 M * 4.12 L =  M₂ * 10.0 L

M₂ = 0.85 M * 4.12 L  / 10.0 L

M₂ = 0.350 M

What is the name of the molecule below?
Arte-miy333 [17]

Answer:

The name of the molecule which is given below is 2-pentene.

Explanation:

Alkenes are the organic compounds which are composed of carbon and hydrogen atoms, in which double bond is present.

In the given diagram:

Each corner and joints shows the carbon atoms and number of carbon atoms in it is 5.

One double bond is present in the 2nd position.

So the compound is 2 pentene.

Hence, 2 pentene is the name of the compound.

One mole of a metallic oxide reacts with one mole of hydrogen to produce two moles of the pure metal
WARRIOR [948]

Answer:

Lithium oxide, Li₂O.  

Explanation:

Hello!  

In this case, according to the given amounts, it is possible to write down the chemical reaction as shown below:

M_2O+H_2\rightarrow 2M+H_2O  

Which means that the metallic oxide has the following formula: M₂O. Next, we can set up the following proportional factors according to the chemical reaction:

5.00gM_2O*\frac{1molM_2O}{(2*X+16)gM_2O}*\frac{2molM}{1molM_2O}*\frac{XgM}{1molM}=2.32gM  

Thus, we perform the operations in order to obtain:

\frac{10X}{(2X+16)}=2.32  

So we solve for x as shown below:

10X=2.32(2X+16)\\\\10X=4.64X+37.12\\\\X=\frac{37.12}{10-4.64}\\\\X= 6.93g/mol  

Whose molar mass corresponds to lithium, and therefore, the metallic oxide is lithium oxide, Li₂O.  

Best regards!
