Answer:
Because you can freeze the water you melted back into a ice cube.
Explanation:
Answer:
2.5×10⁶ s
Explanation:
From the question given above, the following data were obtained:
Rate constant (K) = 2.8×10¯⁷ s¯¹
Half-life (t½) =?
The half-life of a first order reaction is given by:
Half-life (t½) = 0.693 / Rate constant (K)
t½ = 0.693 / K
With the above formula, we can obtain the half-life of the reaction as follow:
Rate constant (K) = 2.8×10¯⁷ s¯¹
Half-life (t½) =?
t½ = 0.693 / K
t½ = 0.693 / 2.8×10¯⁷
t½ = 2.5×10⁶ s
Therefore, the half-life of the reaction is 2.5×10⁶ s
Answer:
The biggest risk with recharging alkaline batteries is leakage. As you probably know, alkaline batteries leak even under normal circumstances. Internal off gassing, made worse by heat, creates pressure that can breach battery seals. Therefore, the risk of leakage is an even bigger risk when recharging.
X-ray
Explanation:
X-rays are used medically by doctors to image the interior of the human body but can cause cell damage.
X-rays are energetic radiations that are classified as ionizing radiations.
They penetrate the skin and body tissues.
- X-rays were discovered by Wilhelm Conrad Röentgen In Germany in the year 1895.
- The rays have a wide range of application today.
- They are used in x-ray therapy to fight cancerous cells in the body.
