Chemical reaction includes chemical changes (modifications in the structures of molecules, new compounds )of the substances in the reaction. As a result of the chemical reaction new substances are formed that cannot be reversed using physical means.

The following method of testing substances is a sure way to identify a chemical reaction:

A. color change

B. Formation of bubbles

D. increase in temperature

A battery has a potential resistance of 12 V and a current of 1280 mA. What is the resistance? PLS HELP ME ASAPPPPPPPPPP

Romashka-Z-Leto [24]

Resistance (R) = 9.375 ohm (Ω)

Steps:

$R = \frac{V}{I}$

$= \frac{12 \: volt}{1280 \: milliampere}$

$= \frac{12 \: volt}{1.28 \: ampare}$

$= 9.375 \: ohm (Ω)$

A 1502.7 kg car is traveling at 33.1 m/s when

Bond [772]

By definition of average acceleration,

a = (20 m/s - 33.1 m/s) / (4.7 s) ≈ -2.78 m/s²

Vertically, the car is in equilibrium, so the net force is equal to the friction force in the direction opposite the car's motion:

∑ F = (1502.7 kg) (-2.78 m/s²) ≈ -4188.38 N ≈ -4200 N

If you just want the magnitude, drop the negative sign.
