Answer:

1.54 × 10⁻¹⁰ m

Explanation:

A number in scientific notation has the form A × 10ⁿ.

A is a number from 1 to 10, but not 10 itself and is called the <em>coefficient</em>.

n is an integer and is called the <em>exponent</em>.

To convert a small decimal number to exponential notation, you move the decimal point to the right until you have one nonzero digit in front of the decimal point.

The exponent is negative of the number of places you moved the decimal point.  

To convert 0.000 000 000 154 m to scientific notation:

  • Move the decimal point to the right until it is just past the 1. The coefficient is 1.54
  • Count the number of places you have moved the decimal (ten). The exponent is -10.

The number in scientific notation is 1.50 × 10⁻¹⁰.

Add the units and the <em>measurement</em> is 1.50 × 10⁻¹⁰ m.

Rory answered that absolute zero is 0°K. Is this answer correct? Explain why or why not.
Ierofanga [76]

Answer:

Yes, this answer is correct.

Explanation:

Absolute zero is -273.15 degrees celsius

T= Tc+273.15

T is the kelvin temperature

Tc is the temperature in degrees celsius

substitute;

T= -273.15 + 273.15

T=0 K

Zn + 2HCI --&gt; ZnCl2 + H2
Elena-2011 [213]
Moles= mass\ relative formula mass(Ar)
moles of zinc= 7.9/30= 0.263
so we have 0.263 moles of zinc, and you need twice the amount of chlorine so therefore 0.526moles of chlorine= 0.526x 17=8.942g of chlorine
i cba to work the rest out but the most reasonable answer is 0.24 mol however if you need to use working outs, use the formula i provided earlier

How many grams is 20 moles of (nh4)2so4 please show work
ryzh [129]

n=20 mol

(NH)4 SO4

Atomic masses :

N- 14

H- 1

S- 32

O- 16

Therefore M= 14×2 + 1×8 + 32 + 16×4

= 132

m= nM

= 20×132

= 2640g
