True or false

Chemistry
1 answer:
Kaylis [27]2 years ago

Answer:

True

Explanation:

<em>Forces</em>, <u>equal in magnitude and opposite in direction</u>, and cancel each other out are called Balanced Forces.

<em>Balanced Forces</em> DO NOT cause any change in the velocity of the object, but the Object may correspond to a change in shape or size.

Example :

<em>Blasting a balloon by compressing it tightly with both hands, roughly with an equal force, is a practical example of Balanced Forces. In this case, the balloon before the burst stays at a state of rest and same after the burst. But the burst or the compression, causes a change in the shape of the balloon.</em>

Reptile [31]

Answer:

Explanation:

250 cm^3 of 0.2 moldm-3 H2SO4 can be prepared from 150cm^3 of 1.0 moldm^-3 by dilution.

150cm^3 of the 1.0 moldm^-3 stock solution is measured out using a measuring cylinder and transferred into a 250 cm^3 standard volumetric flask and made up to mark. The resulting solution is now 250cm^3 of 0.2 moldm-3 H2SO4.
