Answer:
Explanation:
Modern Agriculture - The agricultural practices with modern technique like Fertilizers, Innovative hybrid seed, and utilization of machine call modern Agriculture.
Advantages -
Feeding to the population without scarcity of food grains.
Optimum Utilization of land (Crop intensity more then 300%)
Increased production of food grain.
Global Market - even our mangoes available at US and we are getting California apple too.
Due to factories and Machine use this industry is growing to and empowering good employment.
I hope this helps you :)
Answer:
4.13 moles of Fe will be produced in the reaction
Explanation:
To produce Fe from CO, we need to react Fe₂O₃ and the carbon monoxide.
The reaction is:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
1 mol of iron (III) oxide react to 3 moles of carbon monoxide in order to produce 2 moles of Iron and 3 moles of carbon dioxide.
We assume, the Fe₂O₃ in excess, so we propose this rule of three
3 moles of CO can produce 2 moles of Fe
Therefore 6.20 moles of CO will produce (6.20 . 2)/3 = 4.13 moles of Fe
The correct answer is:
Zinc and hydrochloric acid
Explanation:
Reactants are the opening materials in a chemical reaction. Reactants experience a chemical change in which chemical bonds are destroyed and new ones created to make products. In a chemical equation, reactants are posted on the left side of the arrow, while products are on the right side. If a chemical reaction has an arrow that points both left and right, then things on both sides of the arrow are reactants as well as products .And in above reaction Zinc and hydrochloric acid react and form zinc chloride.

Answer:
yeah it's b
Explanation:
The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. ... The speed of sound in a medium is determined by a combination of the medium's rigidity (or compressibility in gases) and its density.
