How many microliters are in 7.4 x 10^-61 centimeters?
schepotkina [342]

Answer:

Microliters = 7.4\times 10^{-58}

Explanation:

SI unit of volume is liter.

1 dm^{3}=1 liter ..............................(1)

1dm=10cm

1dm^{3} = 1000 cm^{3}.................(2)

replacing value of 1 dm^{3}from equation (1) in equation (2)

1 liter = 1000 cm^{3}...................(3)

but

1 liter = 10^{6} microliters....................(4)

replacing value of 1 liter from equation (3) in equation (4)

1000 cm^{3} = 10^{6} microliters

on solving further ,we get

1 cm^{3} = \frac{10^{6}}{10^{3}}microliter

1 cm^{3} = 1000 microliter

7.4\times 10^{-61}\times 1000

Microliters = 7.4\times 10^{-58}

For the reaction 2HNO3 + Mg(OH)2 → Mg(NO3) 2 + 2H2O, how many grams of magnesium nitrate are produced from 4 grams of nitric aci
kotegsom [21]

Answer:

First check to make sure you have a balanced equation

Second use mole ratios to set up what you need to know

Finally convert the moles to grams using the correct molecular weight

I will get you started

According to the reaction above, one mole of Magnesium Nitrate is produced from 2 moles of Nitric Acid

1 mole of Mg(NO3)2/2 moles of HNO3

5 grams of Nitric acid contains

5 g * 1 mole/63 g of Nitric Acid = 0.079365079 moles

If one body is positively charged and another one is negatively charged free electrons tend to ?
lord [1]

Answer is: Move from the negatively charged body to the positively charged body.

The electron (symbol: e⁻) is a subatomic particle whose electric charge is negative one elementary charge.

The proton (p⁺) is subatomic particle with a positive electric charge of +1e elementary charge.

Opposite charges (positive and negative) attract one another.  

The negatively charged body has extra electrons, more electrons than protons.

The positively charged body has less electrons than protons.
