4.Hi, I would like to know how I can check the concentration of phosphoric acid (V) in descaler product for
t for steamers. I got this: https://www.gastrro.pl/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/6/4/648050.jpg Ingredients: phosphoric acid (V), anionic surfactants less than 5%. Lately my mother/father was cleaning the steamer for food with it and today I've noticed the black residue on the bottom of the water in steamer and I've been eating vegetables from that steamer for like many days and just adding water, didn't replace it fully. Wondering if that could impact my health somehow. I'm a bit nervous, thanks.
5.Hi! My name is Shance and I am starting college in the Fall term. I completed my A.A around 10
ago but due to complication, the school is requesting I take a math course. I have two entrance exams to take, and they're timed. Was wondering if to save time, would it be possible to just get the solutions instead of having it explained to me? I have a exam that is due today around noon my time (EST), and one scheduled for tomorrow. The school is also requesting to speak to me beforehand to make sure that I understand the materials. I would also need help with that. The phone call shouldn't take more than 30 minutes. Once I know that you're able to help me, I will schedule an appointment.
