(Science)<br>(image attached)<br>Pls help, due tmr​
Lelu [443]

Answer:

4-wheeler

Explanation:

I was thinking that you could say this:

My design is that the 4-wheeler will detect, with the help of technology, when something is approaching or you are very close to it. As the object gets closer, it will beep faster and louder. When the 4-wheeler beeps really fast and really loud, it means that you are about to crash or you are in danger. It will stop and launch an airbag so you stay safe. When the 4-wheeler stops, it will make a signal to let people know that you have stopped.

I am so sorry if this wasn't the response that you were looking for.

Hope this helped!

Identify the polyatomic ion and its charge in each compound (a) KNO2 K N O 2 (b) CaSO4 C a S O 4 (c) Mg(NO3)2
g100num [7]

Answer:

Explanation:

Polyatomic ions are ions (usually anions) that are made up of more than one atom. In order to determine the charge of anions, one can first identify the charge of the metal (which forms the cation) in a compound (which is usually easy to know) before predicting the charge of the anion. The charges are usually exchanged to form denominator of the other reacting atom/molecule, but if divisible, they are divided first before the exchange.

(a) The polyatomic ion in KNO₂ is NO₂ with the ionic equation below showing it's charge

KNO₂  ⇒ K⁺ + NO₂⁻

From the above, we can deduce that the charge of NO₂ is "1-"

(b) The polyatomic ion in CaSO₄ is SO₄ with the ionic equation below showing it's charge

CaSO₄ ⇒ Ca²⁺ + SO₄²⁻

The charge of SO₄ from the above equation is "2-"

(c) The polyatomic ion in Mg(NO₃)₂ is NO₃ with the ionic equation below showing it's charge

Mg(NO₃)₂   ⇒ Mg²⁺  +  NO₃⁻

From the above equation, it can be deduced that the charge of NO₃ is "1-"
