Answer:
being responsible is owing up to the possible
consequences of your decision whether it was right or wrong.
communication is a two way process in which there is a messenger and receiver
one of the ways by which a person could be responsible is by saying 'I'
in all the things he would say, instead of 'we'
for example , " We don't like the way you acted a while ago " , change it to i don't like tye way you acted a while ago.
here u r establishing ownership on the things you want to say to the person
Answer:
z+4
Explanation:
An isotope of an element, atomic number Z, has a mass number 2z+4. How many neutrons are there in the nucleus of the element?o
protons + neutrons =mass number
so
z +neutrons = 2z+4
neutrons = 2z+4 - z=z+4 which is the # of neutrons in the nucle
us
Answer:
119.85 grams Br or 120. grams Br (sig figs)
Explanation:
1.50 moles Br 79.90 g Br
--------------------- x ------------------------ = 119.85 grams Br or 120 grams Br (sig figs)
1 mole
170 Im pretty sure. It bounces off at the same angle as it is striked
Hey there!
I assume you want this equation balanced.
Al₂(SO₄)₃ + Ca(OH)₂ → Al(OH)₃ + CaSO₄
Let's start by balancing the polyatomic ions, starting with SO₄.
There are 3 on the left and 1 on the right, so let's add a coefficient of 3 in front of the CaSO₄.
Al₂(SO₄)₃ + Ca(OH)₂ → Al(OH)₃ + 3CaSO₄
Now let's balance the polyatomic ion OH.
There are 2 on the left and 3 on the right, so let's put a coefficient of 3 in front of Ca(OH)₂ and a coefficient of 2 in front of Al(OH)₃.
Al₂(SO₄)₃ + 3Ca(OH)₂ → 2Al(OH)₃ + 3CaSO₄
Now let's balance Al.
There are 2 on the left and 2 on the right, so Al is already balanced.
Lastly, let's balance Ca.
There are 3 on the left and 3 on the right, so Ca is already balanced.
This means we're done! Here's the final balanced equation:
Al₂(SO₄)₃ + 3Ca(OH)₂ → 2Al(OH)₃ + 3CaSO₄
Hope this helps!
