The primary difference between a hypothesis and a theory is that a hypothesis is falsifiable but a theory has been proven to be correct. An hypothesis is a proposed explanation put forward on the basis of limited evidence as a commencement point for further investigation, at the end of the investigation the theory may not be accepted if it failed to meet some criteria. A theory is a proven system of ideas used to explain a particular phenomenon.

Answer:

The correct answer is:

'A hypothesis is falsifiable, but a theory has been proven to be correct'.

Explanation:

<u>Hypothesis:</u>

A hypothesis is a intelligent guess or prediction to interpret or explain any phenomena.

It is tested through the series of experiments and by number of studies to actually decide whether hypothesis is in agreement with observation and results predicted by it. These prediction are made on basis of limited evidences. It can be false or true.

<u>Theory:</u>

A theory is an in depth explanation behind any physical phenomena which has been tested multiple times through the correct scientific methods and experimentation. It will give same results and observations.

What is the correct ionic formula when mg2+ and p3− react?
Mumz [18]

Answer: Ionic formula will be Mg_3P_2.

Explanation: Mg^{2+} and P^{3-} ions will form a ionic compound. Ionic compounds have both metals and non-metals.

Here Mg^{2+} is a metal and P^{3-} is a non-metal.

The net charge on any compound must be 0.

So we need 2 phosphate ions to balance the charge on Mg^{2+} ions. Similarly we need 3 Magnesium ions to balance the charge on P^{3-} ions.

Criss-crossing the charges, we will get the formula as Mg_3P_2

Criss-crossing is shown in the image below.

Consider the chemical equation. CuCl2 + 2NaNO3 mc023-1.jpg Cu(NO3)2 + 2NaCl What is the percent yield of NaCl if 31.0 g of CuCl2
lana [24]
CuCl2 + 2NaNO3 ---->  Cu(NO3)2 + 2NaCl

using molar masses:-
Theoretical yields:-
63.54 + 2(35.45) g  of CuCl2  produces  2(22.98 + 35.45) g of NaCl
    134.44  g .................................................... 116.86 g
       31.0 g ....................................................31.0 * 116.86 /134.44=26.95g  
 
 So percentage yield is 21.2* 100 / 26.95    =  78.7%  to nearest tenth

A typical adult human body contains approximately 2.500 L of blood plasma. How many grams of blood plasma are in the typical adu
kirill115 [55]

Answer:

m=2.575g

Explanation:

Hello,

In this case, since the density is defined as the ratio of the mass and volume:

\rho =\frac{m}{V}

We can compute the mass of blood as follows:

m=\rho *V=1.03g/L*2.500L\\\\m=2.575g

Best regards.

Use the periodic table to select which type of bond is present and which of the listed properties is most likely for each substa
jenyasd209 [6]

Answer:

A = Metallic Bond

B = Strong bonding, strong conductor, high melting and boiling points

Explanation:

Since the bond is between two metals (located in groups 11 and 12), they would experience metallic bonding. Metallically bonded molecules have high melting and boiling points due to the strength of the metallic bond. They also experience strong electrical current due to the there delocalized electrons.
