Answer: both compounds have ionic bond between metal and non-metal
Explanation: both Sr and Mg are earth alkaline metals and form ions Mg^2+
And Sr^2+. Br forms ion Br^- and S ion is S^2+.
Answer:
2m/s²
Explanation:
When an object starts or at its state of rest it has an Initial speed U = 0
Final speed = 6m/s
total time taken for the acceleration = 3s
Acceleration =?
Acceleration is the change in velocity (speed) with time
OR
Time rate of change of velocity
Acceleration = <u>Change in Speed(velocity)</u>
Time taken
Hence,
Acceleration = <u> </u><u> </u><u>V - </u><u>U</u><u> </u><u> </u>
t
a = <u>6</u><u> </u><u>-</u><u> </u><u>0</u>
3
a = <u>6</u><u> </u><u> </u>
3
a = 2m/s²
Answer:
Because photosynthesis ceases due to the lack of sunlight.
Explanation:
Plants typically absorb CO2 and release oxygen, but they also “exhale” CO2, particularly at night, when photosynthesis ceases due to the lack of sunlight. Forests also emit more CO2 when they are stressed by increasing temperatures.
Explanation:
it shows the Neutralization process, Acid (HCl) reacts with base(NaOH) to give salt(NaCl) and water (H2O)
