  • My 19 month old doesn't talk and seems to have sensory issues, plz help?

    My son is 19 months old, says one word Dada thats all. He wont touch food, not pick up even a cookie. He used to be a good eater eating everything, now I have to blend his food in the blender, texture is so important to him. He refuses to self feed anything. I have to feed him everything I can. He will only eat oatmeal, yogurt, pudding, flan, fruit loops cereal, milk, water and anything else I can sneak in those food I do. What can I try to feed him more that he might eat? He hates meat/veggies/pasta +carbs. I give him liquid vitamin drops in his food as he wont eat the chewables. He used to eat all of these food, but past few months he stopped. He passed the autism screening test at 18 months so his Dr said he is fine for now. I'm involved in early intervention, just 2 months ago we started and he's getting speech therapy, developmental therapy and waiting on writen approval to start his occupational therapy. I really want him to blossom and develop as he grows. He loves when I play with him, music time and story time we have together. Any advice on activities I can do with him and ways to improve his eating?

  • plz help with this chemistry problem?

    How many grams of cyanide can be produced?

    Hydrogen cyanide, HCN, can be made by a two-step process. First, ammonia is reacted with O2 to give nitric oxide, NO.

    4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(g)

    Then nitric oxide is reacted with methane, CH4.

    2 NO(g) + 2 CH4(g) → 2 HCN(g) + 2 H2O(g) + H2(g)

    When 27.0 g of ammonia and 25.1 g of methane are used, how many grams of hydrogen cyanide can be produced?
