explain using diagrams how potassium forms the compound potassium flouride when it reacts with flourine
Katarina [22]

Answer:

The answer to your question is given below.

Explanation:

Potassium (K) has 19 electrons with electronic configuration of 2, 8, 8, 1.

Fluorine (F) has 9 electrons with electronic configuration of 2, 7.

Fluorine needs 1 electron to complete it's octet configuration.

Hence, potassium (K), will lose 1 electron to fluorine (F) to form potassium ion (K+) with electronic configuration of 2, 8, 8. The fluorine atom (F) will receive the 1 electron from potassium to form the fluoride ion (F-) with electronic configuration of 2, 8.

How does an embryo develop from a fertilized egg?]
faltersainse [42]

Answer: Hope this helps

<h3>Explanation: <u><em>The fertilized egg zygote divides repeatedly as it moves down the fallopian tube to the uterus. First, the zygote becomes a solid ball of cells. ... Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.</em></u></h3><h3><u><em /></u></h3>

Help needed urgently<br>the word missing or partially seen is oxygen ​ I forgot to put more pointa
butalik [34]

Explanation:

2.04 % hydrogen

32.65% sulphur

65.31% is oxygen

atomic ratio

hydrogen =2.04÷1=2.04

sulphur =32.65÷32=1.02

oxygen =65.31÷16=4.08

simplest ratio

hydrogen = 2.04÷1.02=2

sulphur =1.02÷1.02=1

oxygen =4.08÷1.02=4

empirical formula is H2SO4

If 1,079.75 Joules of heat are added to 77.75 grams of water, by how many degrees Celsius would the water increase? Assume water
djyliett [7]

Answer:

If 1,079.75 Joules of heat are added to 77.75 grams of water, by 3.32 degrees Celsius the temperature of  water will increase

\Delta T=3.32 C^{0}

Explanation:

q = mC\Delta T

Here , q = heat added / removed from the substance

m  = mass of the substance taken

\Delta T = Change in temperature

C = specific heat capacity of the substance

In liquid state the value of C for water is :

4.18 J/gC^{0}

Given values :

q = 1079.75 J

m = 77.75 gram

Insert the value of C, m , q in the given equation

q = mC\Delta T

on transposing ,

\Delta T=\frac{q}{mC}

\Delta T=\frac{1079.75}{77.75\times 4.18}

\Delta T=3.32 C^{0}
