Number of protons in Uranium-235 is 92
Number of neutrons in Uranium- 235 is 143
Explanation:
Isotopes are the two or more elements having the same number of protons and electrons but different number of neutrons. They differ in their atomic masses.
Answer:
An ionic bond.
Explanation:
A strong electrostatic force of attraction will develop between the oppositely charged ions. For example, sodium chloride (salt) is essentially made of a positively charged sodium ion and a negatively charged chloride ion.
The statement given in this question is TRUE; Some animals in grassland can obtain the water they need from plants.
Grassland is a biome that is characterized by wide range of temperature and uniform distribution of rainfall all through the year. The major plants found in the biome are grasses and herbs. The soil in the biome is not fertile enough for trees to survive there. Different animals can be found in the biome and some of the animals has drought resistance capacity. Some of these animals obtain their water requirement from the grasses, which they consume.
Answer: 100mL sucrose solution and 900mL water
Explanation: sucrose solution is 500 mM, i.e. 500mmol/L
water is 0mmol/L
To get 50mmol/L we need 1/10 L of sucrose solution = 100mL
and made up to 1L with water
Answer:
Research
Explanation:
Research is a deliberate attempt to find answer or solution to a problem along with help of observation, study, survey, comparison, literature review and experimentation.
It is in other way a search for knowledge through systematic way of finding solutions to a problem.
The research methodology comprises of following stages –
Stage I – Observing a problem
Stage II – Formulating a hypothesis
Stage III – Collecting the data
Stage IV – Analysis of facts and data
Stage V – Finding a solution or reaching a conclusion
